9:45 a.m. (EDT)

Boston Marathon bomber Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) has entered the courtroom ahead of a hearing where he will formally be sentenced to death.

The 21-year-old Tsarnaev wore a dark sports jacket with a collared shirt and no tie. His beard is fuller than the goatee he sported during the trial. He appeared impassive as he chatted with his lawyers.

The Boston police commissioner and the parents of the youngest bombing victim were also in the courtroom Wednesday.

Three people died and more than 260 others were injured when twin bombs exploded at the finish line of the 2013 marathon.

In May, a federal jury condemned Tsarnaev to die for the bombings.
